In distant Europe, the first toothbrush was born in 1780 or so. One morning in 1780, an English prisoner, William Adith, washed his face and wiped his teeth with a small piece of cloth. Because the cloth was inefficient and unclean, he suddenly came up with the idea of an improved toothbrushing tool: drill some holes in a bone, ask the guards for some hard bristles, cut them off, tie them into small clusters, and apply glue.
